Influence of temperature and food biomass on the development of the Coccinellid beetle Diomus hennesseyi (Coleoptera: Coccinellidae), predator of Phenacoccus manihoti (Homoptera: Pseudococcidae) in intertropical Africa [link]Paper  abstract   bibtex   
The coccinellid Diomus hennesseyi Fuersch is a not well-known predator associated with the cassava mealybug, Phenacoccus manihoti Matile-Ferrero. It was recently recorded for the first time in 1987 in intertropical Africa. Its lifecycle has been studied in the laboratory at constant temperatures and relative humidity (T = 20 degrees C +/- 1 degrees C, 25 degrees C +/- 1 degrees C et 30 degrees C +/- 1 degrees C; HR = 80-90% +/- 5%; Photoperiod = L/D 12/12). The fastest development combined with a lower mortality occurred at 30degrees C. This temperature has been considered to be the optimum temperature for D. henneseyi. Its lower temperature threshold was 9,6 degrees C. During the larval development D. hennesseyi consumed 1,7 mg P. manihoti eggs and reached a maximum weight of 0,51 mg under the experimental conditions.
